Description

Technical Field

[0001] The utility model relates to the technical field of plastic aging tests, in particular to a plastic particle aging test box. Background Art

[0002] The main reason for plastic aging is that the structure or components have internal weaknesses that are prone to aging, such as unsaturated double bonds, side chains, carbonyl groups, hydroxyl groups at the ends, etc. The external or environmental factors are mainly sunlight, oxygen, ozone, heat, water, mechanical stress, high-energy radiation, electricity, industrial gases such as carbon dioxide, hydrogen sulfide, seawater, salt spray, mold, bacteria, insects, etc. In order to test the shelf life of the plastic products produced in the outside world, we generally use aging test chambers to conduct aging tests on the plastic products produced.

[0003] Light, the shorter the light wave, the greater the energy. It is the ultraviolet rays with higher energy that have a destructive effect on rubber and plastics. In addition to directly causing the breakage and cross-linking of rubber molecular chains, ultraviolet rays can also generate free radicals in rubber and plastics due to the absorption of light energy, which triggers and accelerates the oxidation chain reaction process.

[0004] However, most of the UV-accelerated plastic aging test chambers currently used place plastic particles in a box and irradiate them with UV lamps, which keep them still. This will cause the test products to be unevenly irradiated by UV rays. The plastic particles at the bottom cannot receive the irradiation of the UV lamp, which may lead to local aging. To this end, we propose a plastic particle aging test chamber to solve the above problem. Utility Model Content
